The Calendar is great for checking all future posts you have scheduled to got out!
You can access the Calendar by tapping on the Calendar button on the bottom bar. Once the Calendar loads you should see all future posts you have scheduled to go out in an organized list view.
Editing the day and time the post is going out is easy with only just a couple of taps! First tap on the post you want to edit. Once the post loads you will be able to see the caption as well as the date and time below. Tap on either the day or time to change it. Once everything is correct, tap on Update to save your changes.
Additionally, if you need to remove the post from going out, tap on the red trash can icon on the top right!
